In this video, I perform both a CPU and RAM upgrade on this Late-2014 Mac Mini. This particular model was originally a base model, with a 1.4 GHz Core i5 CPU and 4GB of RAM. I upgraded the machine to 16GB of RAM, along with a 3 GHz Core i7 CPU, making it a MUCH better machine. 2014 Mac Mini RAM Upgrade MacRumors Thread: https://forums.macrumors.com/threads/mac-mini-late-2014-ram-upgrade.2338205/
